Enhanced edge extraction using spiral phase plate in optical scanning holography based on gaussian beam apodization [PDF]
Enhanced edge extraction with high resolution is demonstrated in optical scanning holography (OSH) system by manipulating the radius of the spiral phase plate (SPP) to dampen down the sidelobes of the point spread function ...

Scene‐Customized Learning for Multi‐Depth 3D Phase‐Only Hologram Generation
Scene‐customized geometric modeling constructs GM‐4K, a controllable 4K RGB‐D dataset for learning‐based multi‐depth hologram generation. By tuning intensity spectra and depth‐region sampling, the dataset reveals how training‐data statistics affect phase‐only hologram encoding and supports a spectral test framework for evaluating model generalization ...

It is argued that the role of infinite-dimensional asymptotic symmetry groups in gravity theories are essential for a holographic description of gravity and possibly to a resolution of the black hole information paradox. I present a simple toy model in two-dimensional hyperbolic/anti-de Sitter (AdS) space and describe, by very elementary ...

Ambident Reactivity in the Phenyl + NO Radical Recombination
ABSTRACT The recombination reaction of nitric oxide (NO) with radicals via its oxygen atom, rather than the more common nitrogen site, offers an intriguing pathway to the formation of oxynitrenes. The photochemical isomerization of nitroso compounds into their corresponding oxynitrenes may involve such a step.

Relativistic and non-relativistic holography [PDF]
Holography is one of the most interesting developments in String theory in the past few years. In this thesis, we discuss various aspects of the correspondence at the phenomenological and conceptual levels.

Wave-front phase retrieval in transmission electron microscopy via ptychography [PDF]
There are many different strategies that allow the solving of the well-known phase problem corresponding to the loss of phase information during a physical measurement. In microscopy, and, in particular, in transmission electron microscopy, most of these

Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.

Feed particle size evaluation: conventional approach versus digital holography based image analysis
The aim of this study was to evaluate the application of image analysis approach based on digital holography in defining particle size in comparison with the sieve shaker method (sieving method) as reference method.
